Question: I have a permit to connect a 2 kWp solar installation. At this time I have a 1.5 kW inverter. I consider connecting another set of two 250Wp panels with microinverters to increase from 1.5kW to full power of 2 kW. Are the micro

Understanding the EN 50438 for MicroInverter Operation

Understanding the EN 50438 for MicroInverter Operation

The EN 50438 gives the specifications of the Grid parameters. The microiverters are required to operate within the limits of this EN standard.

The parameters mean if the grid frequency is above 52 Hz or bellow 47.5 Hz, the microin
